Firstly, apologies for a) the massive x-post and b) the time taken to get back to people... Please let me know where this is most appropriately dealt with and I'll keep it off other lists, considering the latest information;

Andrew - please note - this is not a problem exclusive to the -mm series, on testing various combos I found it in the stock series too.
